DETAILED DESCRIPTION OF THE REFFERED EMBODIMENT

[0017]FIG. 1 shows the using status of a prior art smoke exhaust machine comprising a prior art smoke exhaust machine1 generally composed of the bellows 11 and the air-extracting leaf 12 to exhaust the soot 5 outdoors. However, the traditional smoke exhaust machine cannot exhaust outdoors completely but bring about the bad smell of oil sludge indoors or in the kitchen. Furthermore, the structure of bellows and air-extracting leaf is not so simple to produce and consume materials. Therefore, the production cost is too high to lower the market competition so neither the producers nor the consumers are able to afford it.

[0018] Referring to FIG. 2 in the jet airstream guidance device 2 of the present invention, a body prop 21 sustains the whole structure of the device. The upside 22 of body prop 21 set a outlet 23 connected with an exhaust pipe to discharge the soot and exhaust out; the downside of the outlet 23 set a suspension guidance appliance 3 (FIG. 3) hanging beneath the upside 22 of body prop in a proper distance to extract the rising exhaust along the airstream baffles 24 out from the outlet 23; the upside and both sides of body prop contain a plurality of tenons 25, 251 to buckle the grooves 241 of airstream baffles 24 so as to easy assemble. Concerning this characteristic, the panel board can be made in different length or width to fit in with varied circumstances. The airstream baffles 24 even can add an airstream baffles behind the body prop to form an airtight space to guide the airstream. Simultaneously referring to FIG. 4, the downside of body prop 21 sets auxiliary bellows 26 which back have an air inlet fan 261 to inhale the outer air into the bellows and set a plurality of air pipes 262 to form an air-rotating device. The streamline mold of auxiliary bellows 26 is to stretch gradually from front to back so as to highly concentrate the exhaust and do not impede cooking. It also takes human engineering into consideration. On the side of auxiliary bellows, here is a control panel 27 comprising operation functions, power status indication and auxiliary lighting equipment. The safety fuse set in the power input control to prevent from the damage of electric appliance.

[0019] Referring to FIG. 3, showing the partial structure of suspension guidance appliance to reinforce the exhaust device. The suspension guidance appliance 3 is at a proper range from the outlet 23 which exhausts the gathered soot outdoors by the rotating fan fast forming the jet airstream. The underside of suspension guidance appliance 3 includes a filter net 31 to protect the user from harm by touching the suspension guidance appliance 3 accidentally. In addition, each leaf of this appliance consumes the electric power around 17 watt so 3 leaves consumes 51 watt excluding other power consumption such as light or intensive wind velocity function. Comparing with power consumption of the traditional smoke exhaust machine, it must much lower and save the energy resources. In order to enhance the exhausting speed and quantity, the suspension guidance appliance can be in accordance with the demand to add up to two or three suspension guidance appliances alongside.

[0020] With the reference of FIG. 4, it is the preferred embodiment drawing of auxiliary bellows. The streamline mold of auxiliary bellows 26 stretches gradually from front to back so as to highly concentrate the exhaust. The rearward of the auxiliary bellows sets an air inlet fan to inhale the outer air into the bellows and set a plurality of air pipes 262 to form an air-rotating device. From the raising air current produced by air pipes 262, the soot push forward to the upper part, suspension guidance appliance 3, to discharge or inhale.

[0021] With the reference of FIG. 5, it Shows the soot 5 produced by general gas-cooker 4. The soot 5 which push upward according to the heat convection principle would not let out but in the protection cover formed by the airstream baffle 24. Furthermore, the soot 5 would be pushed upward by means of the ascended air current formed by the air pipes 262 of auxiliary bellows 26 while approaching the airstream baffle 24; then the downward suspension guidance appliance 3 hanging below the outlet 23 exhausts the soot out and exhaust the those directly pushed upward without passing through the air pipes 262.

[0022] The present invention can adjust the stature by utilizing the stature appliance. That is the motive power component that sets the wheel on the back prop and track on the wall. By means of electric control method regulating the jet airstream guidance device in accordance with the cookers' dimension arranges the space. Or by means of mechanism, it takes the bearing as support to combine the ring screw fixed on the present jet airstream guidance device so that the bearing revolves the present jet airstream guidance device upward and downward.

[0023] Comparing the present invention with the prior art smoke exhaust device, it is provided with more merits as follows:

[0024] 1. Compulsory jet airstream discharges the exhaust outdoors to decrease the liquid substance formed by the quenched reaction of soot cohering on the smoke exhaust device in order to prevent the kitchen contamination from dropping the oil sludge in the cooking utensils to maintain the food hygiene.

[0025] 2. Besides the soot harm the skin, the noise from smoke exhaust machine, pans, slices and so on would aggravate the affliction. The present invention can improve the noisy problem of smoke exhaust machine.
